From the clues posted by Amazon this morning, it appears that the Secret Agent/Danger Man DVD set will be their lightning sale today starting at 6pm (pacific). Lightning sales only last an hour, or until all supplies are claimed, so move quickly if you want to add this must-see series to your library at a discounted price. For more information about the history of the series, see the DVD megaset review on our fellow C.O.B.R.A.S. site, Double O Section here.
